Phys.org / Using peat as sustainable precursor for fuel cell catalyst materials
Iron-nitrogen-carbon catalysts have the potential to replace the more expensive platinum catalysts currently used in fuel cells. This is shown by a study conducted by researchers from the Helmholtz-Zentrum Berlin (HZB), Physikalisch-Technische ...
Tech Xplore / New model measures how AI sycophancy affects chatbot accuracy and rationality
If you've spent any time with ChatGPT or another AI chatbot, you've probably noticed they are intensely, almost overbearingly, agreeable. They apologize, flatter and constantly change their "opinions" to fit yours.
Phys.org / Quantum key distribution enables secure communication via hybrid and mobile channels
As part of the QuNET project, researchers have demonstrated how quantum key distribution works reliably via hybrid and mobile channels. The results are milestones for sovereign, quantum-secured communication in Germany and ...
Phys.org / Covalent organic frameworks grown through coupling reactions unlock new class of semiconducting magnets
Chemists at the National University of Singapore (NUS) have developed a methodology to enable coupling reactions for the growth of crystalline porous covalent organic frameworks, unlocking a new class of semiconducting magnets. ...
Medical Xpress / Newly identified immune cell type could hold key to preventing scar tissue buildup in wounds
Researchers at the University of Arizona have uncovered a previously unknown population of circulating immune cells that play a critical role in fibrosis, the buildup of scar tissue that can lead to organ failure and disfigurement. ...
Phys.org / An important wetland in Ghana is under siege. Researchers investigate the real issues
Wetlands are vital ecological resources that provide several benefits in urban and peri-urban areas. They slow down flood waters, and act as a source of fishing and farming livelihoods. They also provide socio-cultural benefits ...
Phys.org / The mystery of hanging coffins: Are modern Bo people the genetic heirs of an ancient burial tradition?
A new study has uncovered a direct genetic link between ancient practitioners of the Hanging Coffin burial tradition and the modern Bo people in Southwest China. The findings published in Nature Communications offer unprecedented ...
Tech Xplore / LLMs use grammar shortcuts that undermine reasoning, creating reliability risks
Large language models (LLMs) sometimes learn the wrong lessons, according to an MIT study. Rather than answering a query based on domain knowledge, an LLM could respond by leveraging grammatical patterns it learned during ...
Phys.org / Farms could be our secret climate weapon
The world's farms could become one of the most powerful tools in the fight against climate change, according to a new international study led by QUT.
Tech Xplore / Silicon could power the next generation of lithium‑ion batteries
By adding silicon to battery anodes, energy storage can be doubled or even tripled. Ph.D. student Ali Abo Hamad at FSCN Research Center has developed a sustainable method to make silicon suitable for next-generation batteries.
Medical Xpress / Myeloid mimicry enables kidney tumors to resist immunotherapy and worsen rapidly, study finds
Researchers at The University of Texas MD Anderson Cancer Center have found that renal medullary carcinoma (RMC) cells use an adaptive mechanism called "myeloid mimicry" to hide from the immune system and promote disease ...
Medical Xpress / Los Angeles wildfires prompted significantly more virtual medical visits, research finds
When uncontrolled wildfires moved from the foothills above Los Angeles into the densely populated urban areas below in January 2025, evacuation ensued and a thick layer of toxic smoke spread across the region. Air quality ...
